I almost agree with the post but I have a concern for ban of the warping technique due to pausing on IGT.
The warping technique has a potential for saving time on restart the game from checkpoint (e.g. 5-2). Certainly, IGT doesn't calculate times between paused the game to changing any costumes, but I think the technique shouldn't be restricted for that specification. Because I consider the operation of changing costume should belong a speedrun. More faster, more quickly, more rapidly, that's our doing on runs.
And simply, I feel attractive to run videos including techniques to end a game rapidly which has runners knowledge. In case of death earlier than changing costumes, we will choose death. It's on a case-by-case.
That's my opinion. Thanks reagards.
